Use of Traffic Responsive Signals to Address Weather Related and Non-Recurring Congestion, University Transportation Center for Alabama

The purpose of the project is to evaluate the effectiveness of using trafficresponsive/closed-loop signal systems to address weather-related congestion,specifically rain-related. Issues to be addressed include:

The effectiveness of traffic responsive/closed-loop signal systems and determine whether benefits justify the costs of implementation;

Environments and operating regimes under which closed-loop signal systems are most effective at reducing weather-related congestion; and
